..the irritated man. Tom did not answer, and his chums rather marveled, for Tom was not the youth to take abuse quietly. But Tom realized that, through no fault of his own, Professor Skeel had been put to serious inconvenience, and it was no more than just that the lads should make good the damage they had unwittingly done. "Let's set up the cutter, fellows," proposed Tom, after a pause, "and then..

"Jiminy, but this is hot work " exclaimed Bob Layton, as he laid down the hammer he was using and wiped his perspiring forehead. "Hot is right," agreed his friend, Joe Atwood, as he also took a moment's breathing space. "You might almost think it was August instead of early June. Old Sol must have got mixed up in his calendar." "I'd call it a day and knock off right now if we were doing anything else," remarked Bob. "But, somehow, when I get going on this radio business I can't seem to quit. There's something about this wireless that grips a fellow. Work seems like play." "Same here," said Joe. "I guess we're thirty-third degree radio fans all right. I find myself talking radio, thinking radio, dreaming radio. If there was any such thing as radio breakfast food I'd be eating it." "I'm afraid we'll get thin if we wait for that," laughed Bob, picking up his hammer and resuming work on the aerial that they were stringing on the top of his father's barn. "But come along now, old scout, and get a hustle on. We're going to finish this job to-day if it takes a leg." Joe stretched himself lazily.

It is very appropriate at this moment when radio has taken the country by storm, and aroused an enthusiasm never before equaled, that the possibilities for boys in this art should be brought out in the interesting and readable manner shown in the first book of this series. Radio is still a young science, and some of the most remarkable advances in it have been contributed by amateurs - that is, by boy experimenters. It is never too late to start in the fascinating game, and the reward for the successful experimenter is rich both in honor and recompense. Just take the case of E. H. Armstrong, one of the most famous of all the amateurs in this ountry. He started in as a boy at home, in Yonkers, experimenting with home-made apparatus, and discovered the circuit that has revolutionized radio transmission and reception. His circuit has made it possible to broadcast music, and speech, and it has brought him world-wide fame.
